These are live M18 smoke grenades from 1965-1974. They should still work, but since they are 50 years old, don't rely on them for emergency/ rescue use.
Each comes with its original cardboard container. They have been in proper dry storage and are in very good to excelent condition. We have one (Red) which is still sealed within its original container.
We have examples of Red, Yellow, and Green. If you can find Violet (Purple Haze), you will have a complete and valuable collection of all four Kool-Aid flavors; Cherry, Lemon, Lime, and Grape were used as code names for the smoke colors in Vietnam.
All the flavors are somewhat toxic, and Grape was eventually discontinued because it was particularily toxic.
These will ship via UPS ground.
